2 Claims. (Cl. (i5- 53) This invention relatesy to coasters adapted tobe afhxed by pressing same to the foot portion of goblets, glasses,bottles, and similar drinking receptacles to prevent liquid overflow ormoisture condensate thereon from soiling linen, table tops or the handsand clothing of the person using such receptacles.

Low cost of manufacture, simplicity oi construction, and efllciency inperforming the intended protecting function are among the objects andadvantages of the invention.

By this invention a satisfactory protecting de- Ivice of sheet materialis provided at such low cost 'that it may readily be sold, like anordinary paper napkin, for being used a single time and then discarded.

One of the principal objects of the present invention is to provide anabsorbent coaster of extreme simplicity, and one that remains attachedto the glass as long as desired, and from which it can be removed andreapplied to the same or other glass.

The coaster is easily and quickly applied tothe foot of the glass andprovides abase for the glass of considerably larger area. The glass isthus less liable to upset or be tilted and if a small amount of itscontents should drip over they will be taken up by the absorbentcoaster. Owing to the fact that long stemmed glassesl are liable to tipover easily considerable breakage is also prevented.

Other objects, advantages and features of the .invention willhereinafter -be described.

Referring to the accompanying drawing, which l illustrates a preferredembodiment of the inven tion,

Figure 1 is a perspective view of the coaster applied to the baseportion of a goblet,

Fig. 2 is an enlarged fragmental sectional view taken on line '2-2 ofFig. 1,

Fig. 3 is an enlarged iragmental sectional view taken on line 3-3 ofFigure 2.

Figure 4 is a plan view of the coaster showing the cover strip inpartially peeled condition,

Figure 5 is an enlarged sectional view taken on lines 5-5 of Flgure4,

Figure 6 is a fragmental cress sectional view of a modied form oi theinvention.

Referring to the drawing, the coaster comprises a disc-like base III ofpaper having any suitable contour provided with a coated area l I of asultable pressure sensitive adhesive.

'I'he area coated with adhesive may be of any suitable contour. Forexample, it may be circular in shape as illustrated in Figure 4. Apeelable cover strip I2 is applied to the adhesive coated areapreferably having a corresponding ment papeigCellophane and the like andis read# ily peelable from the adhesive coating Il.

Slits`l and I6 are provided in the base sheet as' shown in Figure 4adjacent the adhesive coated area 4 so as to provide a yieldable portionin the base I0 between the said slits.

In using ythe coaster, the cover strip I2 is peeled off and the adhesivearea I4 issimply pressed by the ilngers against the base 6 of the gobletas shown in Figures 1 and 2. The slits I5 and i6 provide a yieldableportion in base I0 thereby permitting the adhesive area I4 to beypressed against the concave faceof the goblet base 6 so y as to bringthe adhesive area I0 into full contact with the base.

I prefer to use a base made of highly absorbent soft paper such asordinary paper napkin stock, several layers being joined together forthis purpose so as to ensure absorption of any. liquids which may dripthereon. If desired, the upper layer may be more absorbent than thelayers therebeneath. The base sheet may be printed or ornamented in anysuitable manner on either one or both sides. The base sheet may also bemade oi cloth, thin veneer, Cellophane, metal foils, Bakelite or otheravailable thin sheet materials. The advantage in using paper-coasters isthat they can be thrown'away after being used once. However, if moreexpensive base materials are used the coasters can be readily vremovedfrom the receptacles and reaiiixed by simply pressing same to the sameor other glasses or receptacles.

adhesive composition may be used for coating an area of the base sheetof paper or other material.vv

Any suitable pressure sensitive normally tacky I prefer to use a hotmelt composition such as disclosed in application Serial No. 98,978.Such composition is thermoplastic and consists essentially of anadhesive agent, a cohesive agent, a mod ier and a common .thermoplasticnon-volaI tile solvent for these agents.

The following composition, for example, is suitable for coating paper:

Per cent by weight Rubber' 15 Vistanex (isobutylene polymer) Y.v. 15Amorphous parailin wax (M. P. 155 F.) 19 Methyl abietate 25 Ester gum-25 Glycerine 0.5 Hydroquinone 0.5

Instead of applying the pressure sensitive ad-l hesive directly to thebase sheet I may provide thin paper 20 coated on bothfaces with pressuresensitive adhesive as shown in Figure 6 and cut therefrom portions ofsuitable area and contour. aud press one face Il of same against thebase sheet I0 so as to retain same onthe base sheet thereby providing anexposed pressure sensitive adhesive area I4 .on the other face foraiiixing the coaster to a glass or other container. I may alsovprovide asheet coated with water soluble glue on onevface and pressure sensitiveadhesive on the other face. Discs or other suitably shaped portions arecut out from this paper which are aflixed to the base sheet I0 bymoistening the glue coated face and amxing same to the base sheetthereby providing an exposed pressure sensitive area on the base. sheet.e

In accordance with the invention I provide a coaster which is'attachableto a glass or the like by simply pressing same into place. It can bereadily removed from the glass by merely peeling it oif and it will notfoul the surface o! the glass or other receptacle to which it may beattached without fouling, marring or leaving a residue o! the adhesive.

It is obvious that numerous changes and moditlcations may be made in thedetails of the invention which are intended tobe included in theappended claims. y

I claim: 1

1. A removable and reusable coaster for drinking glasses and the like,comprising a base sheet of absorbent paper having an area thereof coatedwith a pressure sensitive normally tacky adhesive for removably afllxingthe coaster to a glass andthe like and apeelable cover strip protectingsaid adhesive coating area.

2. A removable and reusable coaster for drinking glasses and the like,comprising a base sheet of absorbent paper, -spaced slits in said basesheet forming a yieldable portion in said base sheet, a coating ofpressure sensitive normally tacky adhesive provided in said yieldableportion for removably amxing the coaster to a glass and the like.
